And notes....

Analogue servos VS Digital, whats the difference?


Analogue servo motors receives a signal from the servos amplifier 30 times a second.

This signal tells the servo motor when to start rotating and which way to rotate.

Since it only happens 30 times a second, that's the minimum reaction time. 


Digital servos send a signal to the servo motor 300 times a second.

Since this signal is received by a digital servo's motor more often, it is able to react much faster and hold its position better.

Digital servos have better centering  and considerably higher holding power.

This power comes at a cost, however, as digital servos tend to draw a lot more power from the on-board battery which means your battery just won't last as long.
